Okay, just a few notes:
* Sorry for sending this rather badly written patch, I have loads of
other stuff at the moment. I hope that it serves as a ground for
further development, though.
* It depends on the e1000_hw.h header from a the Linux kernel driver (look
in drivers/net/e1000), I haven't included this header in the patch.
* As far as I've seen, ICMP ping works, but TCP doesn't (I think it
is because this emulator implementation doesn't do the off-load of
packet checksuming, as the guest expects)
* Several up/downs of the interface while it is working seem to cause
guest memory corruption. Haven't looked into this yet.
Have fun hacking!
